Potential of thermoelectric power generation using anomalous Nernst effect in magnetic materials

This article introduces the concept and advantage of thermoelectric power generation (TEG) using anomalous Nernst effect (ANE). The three-dimensionality of ANE can largely simplify a thermopile structure and realize TEG systems using heat sources with a non-flat surface. The improvement of ZT can be expected because of the orthogonal relationship between thermal and electric conductivities. The calculations of an achievable electric power predicted that an improvement of thermopower by one order of magnitude would open up a usage of practical applications.
